Gnrswopn, a citizen of theUn'ited States, residing at Prov` 0f.Providence and State idence, in the county of Rhode Island, have invented certain new in the art to which it appertalns to make and use the *sama-reference being had to the accompanying drawings, and tolett'ers or gures of reference marked thereon, which form apart of this specification.V Y .15 This invention relates to projectiles adapted to .be charged with dynamite or other analogous explosives; and it consists, essentiallv, of

i Va shell-'having a' conicalv or other well-known b'o exterior form adapted to be inserted within der sfr chambersI and y "packings, the central chamberbeingthe holder for the explosive material, all combined and -arranged within' said outer shell and adapted to be :tired 'from a gun charged with powder, Y as common. a

The object of the invention is to so arrange the dynamite charge Within the projectile,

The operation of loading is as follows: The:4 7opowder-cartridge is first placed within the bore of the gun and rammed home, after which the projectile J, containing the`charge ofdynamite, is inserted and pressediagainst the cartridge. The gun can as usual. l
